7. Legal AI for Indian Context
District courts are usually the first
point of contact between the people
and the judiciary.
Lower courts in India are burdened
with a backlog of cases (~40 million
as of 2021).
Local languages used in the
documents filed in district courts in
India.

8. Legal AI / NLP - Data
We collected ~900k district court case documents from Uttar
Pradesh
All documents in Hindi, written in Devanagari
There are legal corpora for European Court of Justice and Chinese
courts, none for Indian district courts

9. Legal AI / NLP - Data
There are around 300 different case types, table shows the prominent
ones
Majority of the case documents correspond to Bail Applications

Variation in number of case documents per district
Case types in HLDC

10. Legal AI / NLP - Bail Documents
10
District-wise ratio of number of bail applications to total cases

11. Legal AI / NLP - Bail Prediction Model
11
In general, the performance is lower in district-wise settings, possibly due to large
variation across districts
Overall, summarization models perform better than Doc2Vec and simpler
Transformer-based models

12. Legal AI / NLP for Indian Context

HLDC: Hindi Legal Documents Corpus

13. Legal AI / NLP for Indian Context - Takeaways
Indian Legal documents are a rich a source of domain-specific Indic-
language corpora, readily available online.
Multiple tasks still need attention especially for Indian settings
